Where does “deaminase” come from?
I need to trace the etymology chain for "deaminase" based on the provided chain, but I notice the chain given appears to trace "amino" or "ammonia" rather than "deaminase" specifically.
However, "deaminase" is an enzyme (the suffix "-ase" indicates this), and it works by removing amino groups. So the word combines "deamino-" (removing amino) + "-ase" (enzyme).
The chain provided traces back to ammonia's origins. Let me construct the sentence following the rules:
Deaminase, an enzyme that removes amino groups, derives from English amine plus the enzyme suffix -ase, with amine tracing to English ammonia, from Latin sal ammoniacus, ultimately from Proto-Indo-European dwóh₁ meaning two.
